Those are absolutely correct, but don't forget Frostscythe of Lord Ahune, dropped by Ahune, the midsummer fire festival daily boss (summonable in The Slave Pens). It has the same model as those two weapons and the warlock ST quest staff with a blue-ish glow around.

Had this drop in the 'Escape from Durnholde keep" raid. So worth doing old raids for great looking transmogs like this. Quite sick on a Hunter.
